Error during compile

[mcgiritli]

Hi all,

 

As everybody can guess, ı'm quite new to SystemC and SystemC-ams world. Just for practice ı was working on a Sin wave generator example that ı found on internet. it was working at the beginning, ı could able to take a look at my trace files. But some how ı begin to get this error from my compiler. 

I have not change anything about the systemc-ams file on my computer. does anybody have any idea what may cause this error ?

 

kindly help about clearing this , thank you in advance..

The error message is complaining about this line:

#include <systemc-ams>

and says it can't find the systemc-ams.

 

I imagine there is a variable in the Makefile that points to the SystemC AMS code, and the code isn't where the variable points.

 

That Makefile variable may also depend on an environment variable, and perhaps that environment variable is not set?

some other proposed fixes:

• remove the #define SC_INCLUDE_DYNAMIC_PROCESSES as you do not need this
• the method sca_get_time() does not exist, use get_time() instead
• it would be more logical to move the ampl=1000 to the constructor
